⬤ The S&P 500 (SPY) is about to notch its eighth straight monthly gain, putting together the longest unbroken winning streak since 2017–2018. The SPY ETF has been climbing steadily through the second half of 2025, rising from the mid-$500 range to around $690 by late December. As of December 24, SPY was trading near $690.38, holding strong into the final days of the year.
⬤ The monthly chart tells the story—eight green candles in a row showing consistent upward momentum. Earlier in 2025, SPY hit some bumps and dipped briefly before getting back on track. Since then, it's been a steady grind higher, fueled by persistent buying across the broad U.S. equity market. SPY remains the go-to gauge for how U.S. stocks are doing overall, and right now, the signal is pretty clear.
⬤ This eight-month run mirrors what happened in 2017–2018, when the S&P 500 also strung together eight positive months. The current rally has pushed SPY from around $500 earlier this year to nearly $690 now—that's a serious move over several months. Even with some choppy trading along the way, the monthly trend has stayed pointed up.
⬤ The big question now is whether SPY can keep the momentum rolling into 2026 or if it's time for a breather after such a long run. Either way, eight straight green months is a strong show of market confidence.
